Calibration in measurement technology and metrology is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy. Such a standard could be another measurement device of known accuracy, a device generating the quantity to be measured such as a voltage, or a physical artefact, such as a metre ruler. The outcome of the comparison can result in no significant error being noted on the device under test, a significant error being noted but no adjustment made, or an adjustment made to correct the error to an acceptable level. Strictly speaking, the term calibration means just the act of comparison, and does not include any subsequent adjustment. The calibration standard is normally traceable to a national standard held by a National Metrological Institute. BIPM DefinitioneditThe formal definition of calibration by the International Bureau of Weights and Measures BIPM is the following Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties of the calibrated instrument or secondary standard and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication. This definition states that the calibration process is purely a comparison, but introduces the concept of measurement uncertainty in relating the accuracies of the device under test and the standard.

In many countries a National Metrology Institute NMI will exist which will maintain primary standards of measurement the main SI units plus a number of derived units which will be used to provide traceability to customers instruments by calibration. The NMI supports the metrological infrastructure in that country and often others by establishing an unbroken chain, from the top level of standards to an instrument used for measurement. Examples of National Metrology Institutes are NPL in the UK, NIST in the United States, PTB in Germany and many others. Since the Mutual Recognition Agreement was signed it is now straightforward to take traceability from any participating NMI and it is no longer necessary for a company to obtain traceability for measurements from the NMI of the country in which it is situated, such as the National Physical Laboratory in the UK. QualityeditTo improve the quality of the calibration and have the results accepted by outside organizations it is desirable for the calibration and subsequent measurements to be traceable to the internationally defined measurement units. Establishing traceability is accomplished by a formal comparison to a standard which is directly or indirectly related to national standards such as NIST in the USA, international standards, or certified reference materials. This may be done by national standards laboratories operated by the government or by private firms offering metrology services. Quality management systems call for an effective metrology system which includes formal, periodic, and documented calibration of all measuring instruments. ISO 9. 00. 02 and ISO 1. To communicate the quality of a calibration the calibration value is often accompanied by a traceable uncertainty statement to a stated confidence level. This is evaluated through careful uncertainty analysis. Some times a DFS Departure From Spec is required to operate machinery in a degraded state. Whenever this does happen, it must be in writing and authorized by a manager with the technical assistance of a calibration technician. Measuring devices and instruments are categorized according to the physical quantities they are designed to measure. These vary internationally, e. NIST 1. 50 2. G in the U. S. 4 and NABL 1. India. Together, these standards cover instruments that measure various physical quantities such as electromagnetic radiation RF probes, time and frequency intervalometer, ionizing radiation Geiger counter, light light meter, mechanical quantities limit switch, pressure gauge, pressure switch, and, thermodynamic or thermal properties thermometer, temperature controller. The standard instrument for each test device varies accordingly, e.

For example, a thermometer could be calibrated so the error of indication or the correction is determined, and adjusted e. Celsius at specific points on the scale. This is the perception of the instruments end user. However, very few instruments can be adjusted to exactly match the standards they are compared to. For the vast majority of calibrations, the calibration process is actually the comparison of an unknown to a known and recording the results. Basic calibration processeditPurpose and scopeeditThe calibration process begins with the design of the measuring instrument that needs to be calibrated. The design has to be able to hold a calibration through its calibration interval. In other words, the design has to be capable of measurements that are within engineering tolerance when used within the stated environmental conditions over some reasonable period of time. Having a design with these characteristics increases the likelihood of the actual measuring instruments performing as expected. Basically,the purpose of calibration is for maintaining the quality of measurement as well as to ensure the proper working of particular instrument. FrequencyeditThe exact mechanism for assigning tolerance values varies by country and industry type. The measuring equipment manufacturer generally assigns the measurement tolerance, suggests a calibration interval CI and specifies the environmental range of use and storage. The using organization generally assigns the actual calibration interval, which is dependent on this specific measuring equipments likely usage level. The assignment of calibration intervals can be a formal process based on the results of previous calibrations. The standards themselves are not clear on recommended CI values 7ISO 1. A calibration certificate or calibration label shall not contain any recommendation on the calibration interval except where this has been agreed with the customer. This requirement may be superseded by legal regulations. ANSINCSL Z5. ISO 9. Where necessary to ensure valid results, measuring equipment shall. MIL STD 4. 56. 62. More Information.
